Synthesis of 1-O-D-Glucopyranosyl-L-rhamnopyranosides and 5-O-α-L-Rhamnopyranosyl-D-glucofuranose^†

Stereoselective synthesis of 1,1′-linked α-l-lyxopyranosyl β-d-glucopyranoside, the proposed biosynthetic precursor of the FG ring system of avilamycins

“…In contrast to conventional glycoside syntheses, the stereoselective synthesis of non-reducing disaccharides demands for control of stereochemistry at two anomeric centers. [8][9][10][11][12][13][14][15][16][17][18][19][20][21] Accordingly, many syntheses of non-reducing disaccharides lead to mixtures of stereoisomers. In addition, yields in the formation of 1-1 0 -linked disaccharides significantly exceed 50% only in rare cases.…”
